I think some of the brownies/blondies in VCIYCJ call for half a box. Or maybe a quarter box. All I know is that when I make them I always make enough batches to use the whole box, and it's more than one batch.

I've never made sour cream, but there are lots of sour cream recipes online that ask for silken tofu, so you could make one of those.

Or you could make pie! Some of the recipes in VPITS ask for half a box: the maple pecan pie or the Boston cream cake pie, for example. There might be more, I don't know. Or you could always halve one of the other pie recipes that ask for a full box.

Hmmmm, I might try the egg suggestion. Can you do it scrambled? I kinda scooped it out of the box and so slicing is out of the question. I have an awesome cornbread recipe already that I veganized, but I am having chili tonight.
